A pupil from Thames Ditton Junior School was approached by a stranger and offered a lift this morning.
The man claimed to be a friend of the family but did not give a name when asked.
The year 6 student continued on his way unharmed and the incident was reported to police.
The school warned parents and pupils to be vigilant and stressed the importance of pupils informing an adult of any incident which makes them uncomfortable.
A pupil was followed on their way home from Hinchley Wood School on Thursday, January 22.
